TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 310,852, dated January 6, 1885.

T0 at whom it may concern.-

Be it known that I, JOHN F. WoLLENsAK, a citizen of the United States, residing at Chicago, in the county of Cook and State of lllinois, have'invented certain new and useful Improvements in Transom-Lifters, of which the following is a specification.

It has been objected to transom-lifters as heretofore constructed that where a long opcrating-rod is used it is liable to become bent at its lower end or at a point below the lowest guide by the weight of the transom or by carelessness in handling. I propose to overcome this difficulty by sleeving a hollow operatingrod upon along stationary guide-rod,whereby the former is supported throughout its entire length, thus obviating all danger of the bending of either of said rods. This construction also enables the making of transoralitters of any length, on short notice, out of material at all times readily obtained, and without the necessity of having special castings therefor.

In the accompanying drawings, Figure 1 shows my improved lifter applied to a transom; and Fig. 2 is a perspective view of the transonrlifter detached, the operating-rod be ing broken away at one point to show the guide-rod.

A is the guide-rod, which is stationary, and connected to the casing by suitable brackets, as a a. This guide-rod is made enough longer than the operating-rod to permit the latter to travel thereon a sufficient distance to open the transom to its widest extent. The guiderod may be made entire or in two pieces; but in the latter case the free ends are at all times confined by the operating-rod. The operating-rod B is made from a tube or hollow rod, and Wholly or partially surrounds the guiderod A, on which it travels. This operatingrod is connected through suitable meanssuch as the ear-pieces b b-to a lifting-arm, D, the latter being in turn connected to the transom. An additional guide for supporting and locl ing the operating-rod is also shown in the drawings. This guide E may consist of a block having a central aperture sufficient in size to permit the insertion of the operatingrod through it, and is provided with screwflanges e e. It is also provided with a setscrew, F, or other suitable locking device, and it may be located at any convenient point between the ends ofthe guide-rod. More than one of these guides E may be used when made necessary by the length of the device. A thumb-piece,( at the lower end of the operating'rod furnishes means whereby said rod is easily handled while operating. may be hung either at the top, bottom, or center. i

As the operating-rod has substantially a continuous bearing upon the guiderod from the point ofjunction of the lifting-arm to the thumb-piece, the danger of the weight of the transom bending the operating-rod is entirely obviated, and in this my invention is an improvement upon the ordinary transom-lifter, in which the guide-rod is not inclosed or'embraced by the operating-rod;

I do not claim, broadly, a transom-lifter in which the operating-rod is connected with the guide-rod by devices, such as an eye; but my invention is limited more particularly to a construction in which the operating-rod is sleeved and has a continuous bearing on the guide-rod throughout the whole or greater part of its length.

I claim- A transom-lifter having in combination a stationary guide-rod, an operating-rod wholly or partially surrounding the guide-rod and having a continuous bearing thereon, and a lifting-arm, substantially as and for the purpose set forth.
